Answer:
-20.1 degrees Celsius
Step-by-step explanation:
The system started at -12.6 Celsius. It then cooled 7.5 degrees during a reaction. Because it cooled, that means the difference is negative.
-12.6 degrees Celsius - 7.5 degrees Celsius = -20.1 degrees Celsius

Step-by-step explanation:
Answer:
The enlarged height of the photo must be 682 inches
Step-by-step explanation:
A customer wants to enlarge the image by 22 times
Hence, the scale factor = +22
Now, the current height of the photo = 31 inches
Therefore, to find the enlarged height : we need to multiply the scale factor of the required image by the current height of the photo.
Hence, Enlarged Height = 22 × 31
= 682 inches
So, The enlarged height of the photo must be 682 inches
Step-by-step explanation:
(1) x+10y=20, x=20,y=2
(2) 6x+y=-18, x=-3,y=-18
(3) 2x-9y=-36, x=-18,y=4
(4) x=-6,y=-15
(5) x=9,y=12
(6) x=-18,y=-3
(7) x=16,y=-6
(8) x=14,y=8
(9) x=-12,y=9
(10) x=-15,y=-6
(11) x=12,y=10
Answer:
60mm
Step-by-step explanation:
75² - 45² = a
3600
√3600 = 60
a=60 mm
